POWER-DENSE PERMANENT MAGNET (PM) DIRECT-MOUNTED MOTORThe DRS PR series Permanent Magnet (PM) motors are designed to maximize the bene� ts of a direct drive mud pump con� guration. Inherently more ef� cient than a belt drive con� guration a DRS PM machine signi� cantly reduces fuel consumption, reduces parts and maintenance expenditures and reduces the footprint and weight of the pump package.
Since 1985, DRS has been building PM machines and providing rugged motors for drilling applications including top drives. DRS is a world leader in the design and manufacture of advanced electrical machinery focused on providing machines for demanding jobs where ef� cient performance and precise control are required.
BENEFITS • Reduced Maintenance - no belts, sheaves or motor bearings • Direct drive confi guration-reduces fuel consumption • Higher motor effi ciency • Improved safety - no belts, sheaves • Approximately 12% lower weight & 25% lower volume
FEATURES• Permanent Magnet fi eld poles• Synchronous Motor eliminates slip• Air cooled 18 pole stator winding • Class H insulation system• Direct mounted on pump pinion shaft• No motor bearings • IP 54 connection box
OPTIONAL FEATURES
• Encoder• ABS Certifi cation
• Separate connection box for RTD’s & space heaters• 6 Stator RTD’s; Two 100 ohm platinum RTD’s per motor phase• Pressure sensor for blower on verifi cation• Uses common Oil Field blower• IP44 motor housing
• Water cooling • ATEX Certifi cation
